Abstract

The utility model is a jet mixer with one end arranged with a male union and the other end arranged with a bend connected with a straight pipe. An assistant regulating pipe with a male union and a support base are arranged on the straight pipe; a guide block ,a bracket, a rotating core and a bend are arranged on the base, a main regulating pipe with a male union is arranged on the bend; the weld angle of the straight pipe and the pipe joint is 145 degrees to 155 degrees the weld angle of the straight pipe and the assistant regulating pipe is 18 degrees to 22 degrees; smooth transitions are adopted on all the internal structures of the support base, and the horizontal position centerline of the jet-mouth of the rotating core is the same with the centerline of the straight line. The utility model can control the density of the mud more easily, realize remote control, convenient control and reliable performance in the course of operations; the utility model can enable a more even mixture of mud and greatly improve work efficiency.

Description

Jet mixer

Technical field

The utility model relates to a kind of jet mixing device, is a kind of simple and easy mixed sizing device that is mainly used in oil well cementing operation field.

Background technology

Carrying out in the mixed slurry kind equipment of well cementing operation in the oil gas field environment at present, the mode of grey funnel was mixed slurry about most employings added on the circulation manifold, and this mixed slurry mode is difficult in to mix in the slurry process controls mud density.In order to obtain comparatively accurate density value, about addition of required various compositions when the operator has to obtain mixing by calculation mode in advance, and then, finally reaching desired hybrid density by constantly measuring in the mixed process, the process that operates is loaded down with trivial details.Also there is a few devices to adopt ash discharging valve and high energy mixers to mix slurry, though this mode can be controlled dreg discharge amount and amount of water in mixing slurry, but because ash discharging valve and high energy mixers internal construction complexity, in operating process, be easy to block or transmission malfunctioning, this reduces the reliability of execute-in-place greatly; Also there is the problem of maintenance difficult in this cover system in addition.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of new jet mixer, in order to overcome the deficiency of above-mentioned existing like product.It can more easily control mud in operation process density can realize Long-distance Control, and operates conveniently dependable performance: it is more even that it can make mud mix, and operating efficiency is obviously improved.

In order to solve these technical problems, the utility model has adopted following technical scheme.

Its union one end is equipped with female union, and an end connecting bend, elbow link to each other with straight tube again simultaneously, and auxiliary regulating tube and supporting seat are housed on the straight tube, and female union is housed on the auxiliary regulating tube; Guide pad, support, commentaries on classics core and elbow are housed on the supporting seat, the homophony pipe is housed on this elbow, on the homophony pipe female union is housed; Straight tube and union soldering angle are 145 °--155 °, straight tube and auxiliary regulating tube soldering angle are 18 °--and 22 °; The supporting seat internal construction all adopts rounding off, and changes jet horizontal level center line and straight tube centerline collineation on the core.

Change core and be provided with four kinds of jets.

The good effect of the technical program is: the size that (1) can regulate amount of water whenever and wherever possible by main control valve and sub-control valve, and regulate automatically by the water yield and to add the ash amount, it is convenient and reliable to operate.(2) main inlet control valve pipeline transfer core has four kinds of jets, four kinds of jets have different mixed slurry abilities, the mud of four kinds of different densities scopes can be provided,, just can be easy to obtain the mud of desired density in the operation process as long as adjust jet in advance according to the operating mode needs.(3) water and ash can access premixed fully in the tube chamber of jet mixer, and again to stirring in the vessel, it is more even that this not only makes mud mix, and shortened the mixed slurry time greatly, improved operating efficiency at last.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment is provided, the utility model is further described.

Shown in Fig. 1-4, embodiment of the present utility model is by 4 " female union 1,2,30 ° of elbows 3 of union; straight tube 4, auxiliary regulating tube 5,1.5 " female union 6, supporting seat 7, guide pad 8, support 9, " female union 11, homophony pipe 12; elbow 13, lubricating cup 14, O type circle 15 and 16; hole back-up ring 17, screw 18 is formed to change core 10,2.Union 2 one ends are equipped with 4 " female union 1; end connects 30 ° of elbows 3; 30 ° of elbows 3 link to each other with straight tube 4 again simultaneously, and auxiliary regulating tube 5 and supporting seat 7 are housed on the straight tube 4, " the female union 6 of being equipped with 1.5 on the auxiliary regulating tube 5, guide pad 8, support 9 are housed on the supporting seat 7, change core 10, elbow 13, lubricating cup 14, O type circle 15 and hole back-up ring 17, changeing on the core 10 has four jets 19, and O type circle 16 and screw 18 are housed again on it, and homophony pipe 12 is housed on the elbow 13, be equipped with 2 on the homophony pipe 12 " female union 11.

Straight tube 4 is 150 ° with union 2 soldering angles, and straight tube 4 is 20 ° with auxiliary regulating tube 5 soldering angles.

Supporting seat 7 internal constructions all adopt rounding off, and change on the core 10 four jet 19 horizontal level center lines and straight tube 4 centerline collineations.Change core 10 and have four jets, four jets are pressed Fig. 4 position distribution to be changeed on the core 10, and its relative position along the circumferential direction is 45 at interval, can select jet according to the site work needs.

Operating principle when the utility model is used as shown in Figure 4, the rated pressure during this system works is 7-8bar.To change core 10 during work earlier and rotate to needed jet, main control valve be opened and be adjusted to gradually maximum then, simultaneously the sub-control valve be opened, but note only needing to open a bit getting final product, because this control valve only uses as reconciling mud density.After everything is ready, in the dry ash jar, add ash, dry ash will enter in the supporting seat 7 and with current and enter in 2,30 ° of elbows 3 of union, the straight tube 4, has realized more important premixed, enters into to mix through premixed mud at last and has carried out again in the stock tank mixing once more.Detection by on-the-spot density and sub-control valve just can obtain the mud of needed density range at short notice to the adjusting of density.
